CANDY-comune MAcHrNE.

My invention relates to machines for coating candies with chocolate orother material and for forming various markings thereon.

My invention has for one of its severa-lV objects the provision ofmarking meansl so constructed and operated that the marking ridge formedon the candy need only he formed on the top of the candy and not slop4down over the sides as is the case with present -machmes tai-ned. Iprovide' a conveyor for feeding in the candies into thev machine whichwill automatically .position the candies transversely underztlie markingmeans, no matter how the candies may beset upon said conveyor. Thefeeding in conveyor also automatically spaces the v candieslongitudinally. My

marking means consists essentiallyr of lspo'uts suitably mounted to begiven a variety of 1 motions. The chocolate or other coating material isfed through the spouts by `positive means which can shut off the flow`at predetermined intervals. In addition to the feeding' conveyor, Iprovide VVanother conveyor which moves the candies received from the.feeding in conveyor under a chocolate coating tank and from there underthe ina-rkiiig spouts. lliis conveyor .is adapted to have its motionstopped at predetermined- `intervals. -while the marking spouts are.

moved over the candies. Other forms of marking can be accomplished when4loothV conveyor and spouts move simultaneously. v Y

yand the feed screws for said spouts and the A further object ofinyinvention is the provision of means for setting the candies after theyhave been suitably coated and marked upon sheets of paper so that thecandies always come a sutlicient distance back from the edge of thepaper. lith present machines` the candies come out yoften on the edge ofthe paper so that part of the candyliiroject-s off the paper. This is a.con-r stant source of trouble and requires an operatorstime to reset thecandies not fed properly on the paper.v

These vand other objects and advantages are attained as shoivnby thefollowingde-` script-ion and by the construction illustra-ted y ytangular candy showing a diagonal ridge on in tlie accompanying drawingsof which:

Mounted in suitable bearingsin brackets 96, is a shaft97 which carries a pulley 98 fixed vto oneend. Pulley 98 is adapted to be driven by a belt (not shown) from asuit-able source of power. Shaft 97 also has fixed upon it belt cone 99.Below cone 99 is a corresponding cone 101 fixed upon shaft 102. A belt100 connects cones 99 and 101. The various parts of the belt shiftingmechanism, which is well known to the art, are denotedv by numerals 103,104 and 105. Pulley 106 is fixed to the end of shaft 102. Belt 107travels over pulleys 106 and 108. Pulley-108 is fixed to shaft 112 whichcarries also fixed to it, pulley 109. Belt 110 travels over pulleys 109and 111. Pulley 111 is fixed to shaft 89, the same shaft which carriesrotor 95.

To provide further for the even coating of candies 40, conveyor 54 isgiven a vertical shaking motion by mea-ns of roller114 which extendstransversely under the upper run of said conveyor. Roller 114 isrotatably mounted in links 115 near their bottom, one link 115 beinglocated on eachside of `conveyor 54 (Figs. 1, 20 and 21). Each link 115is pivotally connected to ahorizontal link 116 pivotally mounted inframe 42. Each link 116 has a downwardly projecting lug 118 on 'its freeend. Shaft 34 carries which lugs 118 are adapted to bear. The rotationof cams 117 rocks links 116 and through the chain of connections justrecited, shakes roller 114. After' candies 40 pass shaker roller 114they are carried under marking spouts 119, 120, 121,v 122 and 123.

v'.lhe said spouts with the mechanism about to be described are used toform ridges of chocolate on the candies such are illustrated in Figs. 24to 33 inclusive.

Spouts 119 etc. receive their chocolate i from a double walled tank 124havingr inlet and outlet steam pipes 125 and 126 respectively (Figs. 16,17 and 18). Buckets 59,

`besides emptying their cont-ents into tank 55,

spill some of itinto opening 127 of feed tube 128 (Figs. 1 and 2).Located within'feed "tube 128 is feed screw 129 whose rotation forcesthe chocolate entering opening 127 to the other' end of feed tube 128where itspills out upon chute 130 and runs into tank 124 (Figs. 20 and21). Shaft' 82 which carries sprocket 35 for turning bucket chain 36,Valso carries a sprocket 131 which drives chain 133 (Figs. 9 and 14).yChain 133 meshesl with sprocket 134 xed to feed screw 129. Lo-

cated within tank 124 are five vertical tubes one of which is shown at132 Fig. *16, each of the spouts 119, 120 etc. being mounted on such atube. Tubes k132 are rotatably mounted in the `upper and lower portionsof tank 124. VNear the upper end of each tube V132 a gear 248 iscarried. Tube 132 for spout 119 carries fixed to it bevel gear 135 whichmeshes'with bevel gear 136 fixed to short shaft 137 (Figs. 16 and 20).Pulley 138 is also fixed toshort shaft 137. driven by pulley 140 onshaft 141, drives pulley, 138. Shaft 141 carries sprocket 143 fixed uponit. A chain 144 meshes with sprocket 143 and sprocket 145 fixed on shaft34 (Figs. 20 andV 21). Pulley 140 is loosely mounted on shaft v141, butwhen it is desired to rotate spouts 119, 120 etc. sliding clutch 146feathered to shaft 141, is moved into engagement by hand with pulley140. Sliding clutch 146 is maintained in its several positions on shaft141 by means of a setscrew (iiot shown).

W'lien it is desired to rotate the spouts, they all must be ofthe typeofspout 123 (Fig. 1,6). l are not adapted to produce circular marxing whenrotated. The spouts are removable and either type of spout can be useddepending upon'the character of the marking desired. An example of themarkingproduced by rotating a spout of the type of spout 123 is to beseen in Fig. 27.

Located within each tube 132 is Va feed screw 147. A valve rod 148 isset in a hole bored through the entire length of feed screw 147.Theupperend of valve rod 148 is enlarged and threaded to forni a screw149 which is screwed into a corresponding thread in feed Screw 147. Eachof spouts" 119, 120 etc. is formed with a beveled valve seat to and fromwhich the point of valve rod 148 can be screwed thereby regulat-'ng Abelt 139 l Spouts of the type of spout 119 the rate of the flow of thechocolate from the y passes over pulley and pulley 157 loose on shaft141 (Figs. 20 and 21).

Belts 139 and 156 are ,kept tensioued by i means of tension rollers l300rotatably mounted on links 301 v(Figs.`20 and 21). Links 301 are pinconnected to Vlinks 302 pivotally mounted on supporting frames y42.

The mechanism for causing the longitudi nal motion. ot tank 124 is asfollows:- ii'iper cam 10S) (Figs. and 7) is fixed on shaft, .toller 200carried by link 201 pivotallr mounted upon trame L12 rolls upon thesurface ot' wiper cani .109, and is held down in engagement with it bymeans oi spring; i209.. Pin connected to the end of link 201 is avertical rod 203 seen in Figs. l and and shown with'its central portionbroken awa y in Fig. 0. The upper end of vertical rod 202:3 is pinconnected to crank 201 txed to shaft Shaft 205 carries lined to it twocranks 200. Each crank 206 is pin connected to a pitinan 207 which is inturn pin connected to braces 17T and 178 oi tank 124;. iilhen it isdesiredthat tank 121 be given no longitudinal motion as would be thecase for marking the candies 10 as shown in Fic'. 27, vertical rod 2.03can be disconnected from crank 201 by withdrawing the pin between them.

For certain markings on candies 4-,0 such as that shown in Fig. 25,conveyor ort can be keptY in continuous motion while the marking spouts110, 120 etc. are emitting chocolate. F or other markings such as thatshown in Fig. 27, conveyor 5&1 must be brought to a standstilt undersaid spouts. The nieehanisln for moving,r conveyor 5st is astollows-Fixed to the end ot shaft 162i is a sprocket Q08, with whichchain 209 engages. (Figs. (S, 'T and 9). The upper end of chain 200passes over sprocket 2l() loose on shaft i211. See also Fig. S. Locateddirectli7 above shatt- :11 is a clutch bar 2li. (Figs.

Near the other endot shaft Q11 is fixed a. sprocket 24A)` (Fig. 8). Passing over sprocket246-) a chain 218` which engages with a sprocket 210 fixed to a ShaftQ20. Shaft Q20 carries sprockets one o'l which is seen at Fin. 7, whichengage with the chains ot convo?, or Q21. Sha ttf 220 alsocarries asprocket 250 over which chain 223 passes. The other end ofy chain 223passes over a sprocket 224 fixed to shaft 225. Shaft 225 carriessprockets one of which is lSeen at 251 (Fig. 7) which engage with the ofthe paper mounting conveyor 230. CrossV wires 246connect chains 244. Acanvas or oil cloth belt- 252 is fastened between chains 244. Belt 252runs over a stationary support 253. |`When clutch 215 is thrown intoengagement with ratchet wheel 231 (Fig. 8) conveyors 45, 54, 221 and 230aregiven an intermittent feeding motion. The feeding in conveyor isdriven by chain 254 which meshes with sprocket 255 fixed to shaft 256.Shaft 256 has sprockets .fixed to it (not shown) which are driven by thechains of conveyor 54. The other end of chain 254 meshes' with sprocket257 fixed to shaft 258 which carries sprockets 4G (Fig. 12) meshing withchains 45. Ratchet wheel 231 is loose on shaft 211. Pawl `232 is carriedby gear 233 which is also loose ony shaft 211. Rack 234 (Figs. 6, 7and.8) meshes with gear 233. vWhen rack 234 is reciprocated as will beexplained, gear 233 is rotated back and forth. The teeth (not seen) onratchet wheel 231 are so cut that pawl 232 only actuates it when saidpawl moves on its upward stroke. The lower end of rack 234 is pinconnected to pitman 235, which in turn is pin connected Vto crank 236fixed to shaft 38.

After candies 40 passfrom under mark-- 55 is very messy. By passingcandies 40 to conveyor 221, no excess chocolate is present when thecandies come upon paper sheet 237 mounted upon conveyor 230. Conveyor230 is provided With flaps 238 (Fig. 13) under which the forward ends ofpaper sheets 237 are inserted'. Because all the conveyors of the machineare geared together, their movements are in spaced relation, whereby itis predetermined that when candies 40 come upon a paper sheet 237 theydo not come partly off its edge but a reasonable distance backtherefrom. Paper sheets 237 when covered with candies are removed fromconveyor 23() by hand and fresh sheets inserted. Conveyor 230 passesover rollers 239, 229 and 240. In order to retain paper sheets 237 inplace, the lower run of belt 252 is held up by the upper run of canvasbelt 241 running on rollers 242 and 243.

The operation of the machine is as follows z-Lever 71 is moved throwingin clutch and starting the motion of the various parts ofthe machine.`The vcandies 40 are placed at random on surface 43 of the feeding inconveyor. along, space the candies longitudinally and wires 47 get themin transverse alignmentl with marking spouts 119, 120, etc. The candiespass over rolls 53 on to conveyor 54 which has its driving mechanism setso'that it is in constant motion when plain candies as in Fig. 23arerdesiredor when candiesY .marked as in Figs. 25, 30 and 32 aredesired.

For conveyor` 54, and the other conveyors geared to it as hereinbeforedescribed, to be in constant motion, clutch 216 is set in engagementwithsprocket 210.A Conveyor 54 moves the candies under slot 58 of chocolatetank 55' which causes their tops andsides to be coated with chocolate,the bottom of the candies receiving their coating by passing over rolls83 and 84. Passing on still fur` ther, the candies come under the actionof blower 87, whereby their coating is evened off and reduced Vto thedesired thickness. The candies then pass under marking spouts 119, 120,etc., which are adapted if desired to have their chocolate feed screws147 operate so that chocolate is only emitted during the time that theVtops of the candies are Vunder the spouts, the chocolate feed beingcontrolled by the actionrof cam 163. Vhen it is desired to havethe'spouts discharge chocolate continuously, set screw'246 (Fig. 21) isreleased from shaft 142 and clutch 15S held into engagement with pulley157 (Fig. 20) by means of a set screw (not seen) on shaft 141. Afterpassing from under the marking spouts, the candies aretransferred toconveyor 221 from whence they pass upon sheets of paper 237 carriedbyrpaper mounting conveyor 230. The sheets of paper with the candiesthereon are then removed by hand for packing. l

If it be desired to'mark the candies as in Figs. 27 and 28, theconveyors must be stopped at intervals with a row of candies under the'marking spouts, and the marking spouts then be given their desiredmotion. In the case ofthe circular marking of Fig. 27, all the spoutsare of the form of spout 123, Fig. 16. By setting clutch 146 inengagement With pulley 140, the spouts are kept in rotation, theVchocolate only being discharged for an interval long enough to form acom- Vires V44 as they move plete circle, the discharge as explained before being controlled by feed screws 147 and cam 163. f For a diagonalmarking asl in Fig. 28, the spouts are kept from rotation, 'l

tal

governed by the inclination of cam 185 (Figs. 'lo and 1T). Thelongitudinal motion oi" the marking tank 122i and its spouts iscontrolledby wiper cam 199 (Fig. T) whose action is brought into playwhen once vertical rod 203 is manually connected to cranl .ltll byinserting the pin between them.

lhen it is desired to give the candies marking as shown in Figs. 3() andthe conveyors are caused to be given continuous motion by setting clutch216 in engagement with sprocket 2l() and bringing about a reciprocatingtransverse motion of marking tank l124; and its spouts. Normally whenthe reciprocating t'ansiierse motion ol' marking tank 121i is notrequired, pitman 19? is disconnected from `trame 177 (Figs. lli and 1T)which permits spring 198 to hold said tank to the right, cam 185 beingset pa lallelto trame 49. lVhen pitman 19? is connected to i'rame 17T,the rotation oi crank 19o on shaft 195 causes the reciprocation otmarking tank 1245 and its spouts, the length ol stroke being controlledby the position oi one end of pitman` 197 in the sloto crank 196;

Any excess chocolate 'trom tank 55 and conveyorldrips down upon inclinedguides `from whence it `runs `back into vat Gil.

lfhe forms of marking shown on the candies in Figs. Q-l to 33 are merelyby Way ol' example. Other 'terms can be obtained by varyingthclength ofstroke ot' the transverse motion, the speed ot' the conveyors and oftransverse stroke and the shape and inclination of cam 185.
